Fig. 5

AG and its variation rate at six AG points in SE-AK from 2006 to 2015. Green/red circles indicate the AG before/after the effects of hydrological and coseismic gravity changes were corrected. An arbitrary constant value was subtracted from the AG for each gravity point, so as to draw all of the AG data in this figure. Note that the AG at RUSG in 2012 was not shown because of the large error associated with the instrumental failure. The vertical bar for each red circle indicates the error value of the corresponding AG data calculated as the root sum square of SD and UC (see Table 2). The red line for each AG point indicates the regression line to the AG measured from 2006 to 2015 (red circles) and its variation rate with its standard deviation is shown as a red value on the right side of the figure. For the gravity point of MGVC, the amplitude of the gravity step between 2008 and 2012 was also calculated associated with the relocation of the gravity point in Mendenhall Glacier Visitor Center. Gray-colored values on the right side of the figure indicate the gravity variation rates determined in the earlier studies (Sun et al. 2010; Sato et al. 2012)
